Figures 1–2

Description. Male. Body medium. Head. Face smooth (Fig. 1A). Fastigium verticis projecting forward (Fig. 1B), dorsal surface furrowed along the midline, apices slightly separated from each other (Fig. 1B). Eyes ovoid, protruding forward; median ocellus elliptical, larger than lateral ocelli (Fig. 1A); lateral ocelli subcircular (Fig. 1B). Apical segments of maxillary palpi longer than subapical ones (Fig. 1C).

Thorax. Anterior margin of pronotum substraight, posterior margin protruding backward and widely rounded (Fig. 1C); lateral lobes longer than deep (Fig. 1C). Posterior margin of mesonotum protruding backward, posterior margin of metanotum faintly protruding (Fig. 1B).

Legs. Fore coxae with 1 spine; femora with 1 short internal spine; tibiae with 1 internal and 1–2 external spines ventrally, apices with 1 pair of spines on ventral surface. Middle femora with 1 pair of apical spines; tibiae dorsally with 1–2 internal and 2 external spines, ventral surface with 1–2 internal and 2–3 external spines, apices with 1 pair of spines on dorsal and ventral surfaces separately. Hind femora with 1 small internal spine; tibiae dorsally with 20–23 internal spines, 21–24 external spines and 1 pair of small subapical spines, apices with 1 pair of dorsal and 2 pairs of ventral spines; basitarsi with 6–8 small spines and 1 apical spine on dorsal surface along the midline (Fig. 1F).

Abdomen. Posterior margin of tenth abdominal tergite concave. Epiproct prolonged downwards, dorsal surface with raised and converging lateral margins, between them concave (Fig. 1H, I); apical margin of epiproct with 1 pair of slender spines on posteriolateral angles, its apices directing downwards (Fig. 1G). Paraprocts prolonged into a thin spine, its upcurved behind middle area (Fig. 1K). Subgenital plate wider than long, posterior margin arched; styli subconical, longer than the plate and inserted on posterolateral areas (Fig. 1L), apices obtuse.

Female. Tenth abdominal tergite concave on dorsal surface with median furrow extending to the apical margin of epiproct (Fig. 2F). Epiproct ligulate, apical margin rounded (Fig. 2G). Cerci slender, gradually upcurved. Subgenital plate semicircular, apical margin bilobate, the lateral lobes rounded (Fig. 2H). Ovipositor about 0.6 times as long as length of hind femur, base stout, moderately upcurved, apices acute; dorsal valvulae longer than ventral ones (Fig. 2G).

Coloration. Male body brown, fastigium verticis and eyes black. Ocelli pale yellow.

Material examined. Holotype: male, Dulongjiang, Gongshan, Yunnan, August 23, 2024, coll. by Yanting Qin and Ting Luo. Paratypes: 1 female, Dulongjiang, Gongshan, Yunnan, August 21, 2024, coll. by Yanting Qin and Ting Luo; 1 female, Dulongjiang, Gongshan, Yunnan, August 22, 2024, coll. by Yanting Qin and Ting Luo; 4 males, Dulongjiang, Gongshan, Yunnan, August 24, 2024, coll. by Yanting Qin and Ting Luo.

Distribution. Yunnan (Gongshan).

Discussion. The new species differs from Rhaphidophora cylindra Li & Bian, 2024 in the following: body brown; dorsal surface of male epiproct with raised lateral margins which sub-parallel in lateral view (Fig. 1H), posterolateral angles with 1 pair of slender spines (Fig. 1I); styli of male subgenital plate conical, longer than the plate (Fig. 1L); female subgenital plate semicircular, apical margin bilobate, the lateral lobes rounded (Fig. 2H).

Etymology. The species is named referring the female subgental plate with bilobate apical margin.
